NATIONAL BESTSELLER - Humanity is under assault by malevolent "antimemes"--ideas that attack memory, identity, and the fabric of reality itself--in this whip-smart tale of science-fiction horror, an entirely reimagined and expanded version of the beloved online novel. <p/>"Utterly brilliant . . . a dazzling, confusing novel with a highly effective, creeping sense of dread . . . I can't recommend it enough."--Charlie Jane Anders, The Washington Post <p/>"[An] unforgettable, mind-bendingly brilliant novel."--The Guardian <p/>They're all around us, hiding in plain sight. <p/>One could be in the room with you now, just to your left. You could be seeing it right now--but from this second to the next, you'll forget that you did. If you managed to jot down a note, the paper would look blank to you afterward. <p/>These entities can feed on your most cherished memories, the things that make you you--and you'll never even know anything changed. <p/>They can turn you into a living ghost--make it so you're standing next to your spouse, screaming in their ear, and they won't know you're there. <p/>They're predators equipped with the ultimate camouflage, living black holes for information, able to consume our very memories of their existence. <p/>And they aren't just feeding on us. They're invading. <p/>But how do you fight an enemy when you can never even know that you're at war? How do you contain something you can't record or remember? <p/>Welcome to the Antimemetics Division. <p/>No, this is not your first day.
